drm: use c99 initializers in structures
Author: Julia Lawall <Julia.Lawall@lip6.fr> Use c99 initializers for structures. Drop 0 initializers in drivers/gpu/drm/sti/sti_vtac.c. A 0x0 initializer is left in vtac_mode_aux in drivers/gpu/drm/sti/sti_vtac.c to highlight the relation to vtac_mode_main. A simplified version of the semantic match that finds the first problem is as follows: (http://coccinelle.lip6.fr/) // @decl@ identifier i1,fld; type T; field list[n] fs; @@ …

sched/fair: Replace rcu_assign_pointer() with RCU_INIT_POINTER()
Author: Andreea-Cristina Bernat <bernat.ada@gmail.com> The use of « rcu_assign_pointer() » is NULLing out the pointer. According to RCU_INIT_POINTER()’s block comment: « 1. This use of RCU_INIT_POINTER() is NULLing out the pointer » it is better to use it instead of rcu_assign_pointer() because it has a smaller overhead. The following Coccinelle semantic patch was used: @@ @@ – rcu_assign_pointer + …
